msm: mdss: check for split display flag during LM allocation



Command mode split display is only supported on DSPP0 and
DSPP1. The current software logic doesn't check for split
display flag causing mixer allocation failure for single DSI
command mode panels on LM-1. Add the check to take care
of this.
